Abstract
The authors report measurements of the 6Li and 7Li diffusion coefficient DNMR in both natural Li and enriched 6Li by the NMR pulsed magnetic field gradient techniques. Between 350 K and the melting point (454 K) DNMR obeys an Arrhenius law with an average activation energy of 0.561+or-0.002 eV. The isotope effect can be explained in terms of classical statistics (mass dependence of the attempt frequency). By combining their DNMR data with the uncorrelated self-diffusion coefficient DSD determined by NMR spin-lattice relaxation measurements they obtain the effective correlation factor which decreases with rising temperature.
